Quick Watt Usage Questions

I knew when I first bought my PSU that it was a little low compared to the PSU calculated for my setup. Then I got a new case with 4 more fans, and added an SSD.

My PSU recently broke while I was playing a highly demanding game, and now I want to do a little research to see if it had to do with asking too much of the PSU.

My question is this. I have a modular, 650w 'active' and/or 'continuous' PSU. If I buy a watt meter, does that mean I won't get any good information about how much power the system is using while idle or full load because it is constantly sucking up 650w? Or does the amount of power it pulls out of the wall fluctuate regardless of this "active" / "continuous" product description?

This is the PSU.

(As a side question...can I monitor watt usage in real time using Performance Monitor -> Power Meter? Do I not need to buy the physical watt meter?)
 
Solution
2*460=340W aprox
CPU=130W

RAM should arround 5W per module (30W) + HDD and SSD each 10W per device (30W) optical 20-25 (25 :) )

So 12V rail should be able to handle about 45 amps for stable and long PSU life. So you'll need at least 650W quality PSU to run this rig.

You can go for it, but i would not buy nothing under 750W branded PSU to ensure long life if I were you. Better safe than sorry.

Best regards :)

Real monitoring is not really possible unless you connect bunch of multimeters and osciloskops. Problem is that you need to see stability of output, on each rail and voltage/current on each rail. So it's not that easy. No program will ensure you correct info.

Provide system info and PSU you had so we could determine if overload is cause of mailfunction.

Calculation of PSU is not about watts. It's about 3.3V, 5V and 12V rails and how much they can deliver. Most concernes should be pointed to 12V rail. Amps provided on that rail should be a bit higher than your CPU and GPU demands, 5V amps should be higher than your disks and fans need. Combined 12V + 5V wattage should be lower than rated PSU power in order to make it work normally.

Supply provided by link is great one. It can run 125W CPU and monster GPU without any problem, but you need to provide more info about your system.
Always go for branded (tested) models when considering to buy PSU.

Best regards :)

That's the one I was thinking of.





Wow okay I didn't know that.
I'm running:

i7-930 at 2.8Ghz (stock)
6GB tripple channel DDR3 1600 ram @1.65V
2 x 1TB HDD, one 3gb/s one 6gb/s
60GB SSD 6gb/s
2 x GTX460 1GB video cards
6 x 120mm fan
ASUS P6X58D-E motherboard

Well I have the 650w one from the first post. So I guess I should upgrade...

I appreciate the advice. This is definitely one area I can stand to learn more about.
